I refer to this just about every week for my OotA campaign. Some ideas don't work for my group (e.g. the suggestion of teleportation circles), but everything here definitely gives me stuff to think about when preparing. And, given the famously poor editing of the adventure itself, Ruiz has done an admirable job of collecting things together in a way that helps the rest of us make sense of the material.
